| Abstract(in English) | For APMC2014 Student Design Competition, a GaN-HEMT amplifier was designed. First, a basic amplifier that does not take care of harmonics was designed and its small signal performance and large signal performance were confirmed. Especially, differences of stabilization circuits for preventing oscillation were considered by simulation. A circuit for preventing oscillation, which does not affect the performance at desired frequency, was selected. Then, class-F amplifier, in which the second harmonic and the third harmonic are processed by load circuit, was developed. The developed amplifier showed very good performance with output power of 8.7W and power added efficiency (PAE) of 54.8%. In this report, design procedure of class-F load circuit and performance of the developed class-F amplifier are described. |
